Prandium

Prandium is a Dead World. It used to be part of the Ultramarines empire of Ultramar in the Ultima Segmentum

Originally a world teeming with life, it was colonised by explorers from Macragge after the Horus Heresy. The planet quickly became the jewel of Ultramar and prospered until it was consumed by Hive Fleet Behemoth 745.M41.

Now, after all life was removed, it is dead. Even the atmosphere was consumed by the Tyranids. The Ultramarines, led by Marneus Calgar, put up a defence but was hopelessly defeated. Once the planet was consumed, the Ultramarines felt a deep sorrow and blamed themselves for its destruction, as it was under the defence of Ultramar, and they had failed.

It is the last in a trail of four dead worlds left in the wake of Hive Fleet Behemoth; Valos, Tyran, Thandros and Prandium.
